[sane-devel] new backend added

[m. allan noah]

I've just committed the kvs40xx backend, originally written by
Panasonic Russia. It covers three models: KV-S4065, 4085 and 7075. I
did have to make some modifications to reduce the large number of gcc
warnings and errors, and it is untested. Please let me know if the
compilation causes you any problems.
